      abstract     = {Heat girdling is a method to estimate the relative
                      contribution of phloem vs xylem water flow to fruit growth.
                      The heat girdling process is assumed to destroy all living
                      tissues, including the phloem, without affecting xylem
                      conductivity. However, to date, the assumption that xylem is
                      not affected by heat girdling remains unproven. * In this
                      study, we used in vivo magnetic resonance imaging (MRI)
                      velocimetry to test if heat girdling can cause xylem vessels
                      to embolize or affect xylem water flow characteristics in
                      the peduncle of tomato (Solanum lycopersicum cv Dirk). *
                      Anatomical and MRI data indicated that, at the site of
                      girdling, all living tissues were disrupted, but that the
                      functionality of the xylem remained unchanged. MRI
                      velocimetry showed that the volume flow through the
                      secondary xylem was not impeded by heat girdling in either
                      the short or the long term (up to 91 h after girdling). *
                      This study provides support for the hypothesis that in the
                      tomato peduncle the integrity and functionality of the xylem
                      remain unaffected by heat girdling. It therefore confirms
                      the validity of the heat girdling technique as a means to
                      estimate relative contributions of xylem and phloem water
                      flow to fruit growth.},
